       Must be greater than the longest line (in characters) to be found in
       the CSV file (allowing for trailing line-end characters). It became
       optional in PHP 5. Omitting this parameter (or setting it to 0 in PHP
       5.1.0 and later) the maximum line length is not limited, which is
       slightly slower.
